The loop is correct, you just need to make sure that your result is computed
and stored as the n-th element that is returned by the loop. Pick up any
manual of R, and looping will be explained there. Also, I would recommend
that you draw a random number for every iteration of the loop. Defining the
random vectors outside the loop make sense to me only if they are the same
length as n.


for (n in 1:1000) { 
task1 <- runif(1, min=0.8, max= 0.9) 
task2 <- runif(1, min=0.75, max= 0.85) 
task3 <- runif(1, min=0.81, max= 0.89)

If you wanted to store the individual probabilities (task1..3), you would
proceed accordingly by defining them outside the loop and storing the value
in the loop as the n-th element of that vector just like for prob.
